なしに / なしでnashi ni / nashi de“without; without doing”

なしに / なしで means without; without doing ~. It is a JLPT N1 Japanese grammar pattern used to say that an action happens without the usual condition, item, or preliminary step.

This grammar point often appears in formal writing, arguments, instructions, and JLPT N1 reading passages. If you want to express that something occurs in the absence of something else, なしに / なしで is a useful pattern to learn because it adds natural precision to your Japanese.

What does なしに / なしで mean?

Use なしに / なしで when you want to say that an action happens without the usual condition, item, or preliminary step.

Natural translations include:

• without
• without (doing) ~

How to form なしに / なしで

Examples of the pattern:

• 断る(ことわる) + なしに → 断り(ことわり)なしに (without asking / without notice)
• 許可(きょか) + なしで → 許可(きょか)なしで (without permission)
• お金(かね) + なしに → お金(かね)なしに (without money)

The form before the grammar point is always a dictionary-form verb or a noun. In JLPT questions, the wrong answer choices often use a ない-form or other conjugation — those are incorrect here.

When is なしに / なしで used?

Use なしに / なしで in situations like:

• stating a condition that is missing (“without X, Y happens”)
• describing something done without the expected preliminary step
• emphasizing that even the absence of something does not change the outcome

Tone and register:

• slightly formal; very common in written Japanese, rules, and objective statements
• なしに feels slightly more literary than なしで, but both are used in everyday formal contexts
• Common in test questions, essays, instructions, and JLPT N1 reading

なしに / なしで example sentences

After reading each sentence, ask what job なしに / なしで is doing: it marks the missing element that would normally be present.

Nuance of なしに / なしで

The key nuance is an action happens without the usual condition, item, or preliminary step.

For example:

• なしに often carries a slightly formal or written tone, while なしで is used more freely in speech.
• When you attach は or も (なしには / なしでも), the sentence emphasizes that even without X, Y is true — or that without X, Y is impossible. This contrasts with plain negative patterns like ないで / ずに, which only describe the non-performance of an action.

なしに / なしで vs ずに / ないで

Both なしに / なしで and ずに / ないで can express “without doing,” but they are different.

なしに / なしで:

• attaches to nouns and dictionary-form verbs
• emphasizes the absence of a condition, thing, or prior step
• often used in formal writing, rules, and objective statements

ずに / ないで:

• attaches only to verbs (negative stem)
• simply describes not performing an action while another happens
• neutral register, everyday speech

When you want to emphasize the missing item or prerequisite, choose なしに / なしで. When you simply want to say “without doing the action of getting permission,” use ずに / ないで.

A helpful practice method is to take a sentence with ずに / ないで and rewrite it using なしに / なしで (by nominalizing the action).
